Terminal Description
pin
1: VSS 1
: Digital system ground.
pin
2: Xtal IN
: Connect the crystal to generate the internal syn-
chronization signal.
Or input an external clock (2fsc or 4fsc).
pin
3: Xtal OUT
: Connect the crystal.
pin
4: CTRL 1
: Inputs the crystal/oscillator selection signal.
Low = crystal oscillator mode.

: This terminal outputs the blank signal.
pin
6: OSC IN
: Connect the coil and capacitor to form the os-
cillator that generates the dot clock.
pin
7: OSC OUT
: Connect the coil and capacitor to form the os-
cillator that generates the dot clock.
pin
8: CHARA
: Outputs the character signal.
pin
9: CS

circuit.
pin 18: SEP C
: Sync separator circuit bias voltage monitor pin.
pin 19: SEP OUT
: Built-in sync separator circuit composite sync sig-
nal output.
pin 20: SEP IN
: Inputs a vertical synchronization signal created
by integrating the SEP OUT pin output signal.
pin 21: CTRL 2
: NTSC/PAL-M switching input.
High = PAL-M format.
Low = NTSC format.
pin 22: CTRL 3
: SEPIN input control.
High = V-SYNC not input.
